Chrysanthemum plant named ‘00-100-216’

ABSTRACT

A new cultivar of  chrysanthemum , ‘00-100-216’, characterized by it&#39;s early blooming habit with frost tolerant single daisy-type inflorescences with maroon red ray florets and gold disk florets, its vigorous shrub-like growth habit after two years of growth, its tight cushion plant form attained without pinching, and its good garden performance and winter hardiness.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH

This invention was made with government support under MIN-21-50 and MIN-21-52 awarded by the U.S. Dept. of Agriculture. The government has certain rights in the invention.

Botanical classification: Chrysanthemum×hybrida.

Variety denomination: ‘00-100-216’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of garden chrysanthemum plant, botanically known as Chrysanthemum×hybrida ‘00-100-216’ and will be referred to hereinafter by its cultivar name, ‘00-100-216’. The new cultivar is commercially known as a garden-type chrysanthemum.

‘00-100-216’ was derived from an on going controlled breeding program that focuses on obtaining new cultivars of garden chrysanthemums in a range of flower colors that exhibit superior winter hardiness for northern climates, a large shrub-like habit in successive growth years that, and a tight cushion plant habit without the need for pruning or pinching. The breeding originally commenced with crosses utilizing Dendranthema weyrichii ‘Pink Bomb’ (not patented) and various unpatented cultivars of Dendranthema×grandiflora.

The new cultivar, ‘00-100-216’, was created with a series of crosses and selections made over a period of years between 1986 and 2000 utilizing proprietary selections. ‘00-100-216’ ultimately originated from a cross-pollination made in 2000 of proprietary seedling designated as ‘89-98-13’ (not patented) as the female parent and the proprietary seedling designated as ‘00-100-352’ (not patented) as the male parent. The new chrysanthemum was selected as a single plant within the progeny of the stated cross in 2000 by the inventor in St. Paul, Minn. ‘00-100-216’ was selected as unique for its single, daisy-type inflorescences with maroon red ray florets and gold disk florets combined with the characteristics that fit the objectives of the breeding program.

Asexual reproduction of the new cultivar was first accomplished via stem cuttings in St. Paul, Minn. in 2001. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar of chrysanthemum. These attributes in combination distinguish ‘00-100-216’ as unique from and all other varieties of chrysanthemum known to the inventor.

-   -   1. ‘00-100-216’ is early blooming and exhibits single daisy-type         inflorescences with maroon red ray florets and gold disk         florets.     -   2. ‘00-100-216’ attains a large shrub-like habit in the second         and successive years of growth attaining about 37.5 cm in height         and 53 cm in width in the first year and about 44 cm in height         and 89 cm in width in the second year.     -   3. ‘00-100-216’ forms a tight cushion plant form without the         need for pinching or pruning.     -   4. ‘00-100-216’ exhibits extreme hybrid vigor.     -   5. ‘00-100-216’ exhibits a massive floral display in its second         and subsequent years after planting.     -   6. ‘00-100-216’ is a winter hardy shrub chrysanthemum with         hardiness to U.S.D.A. Zone 3.     -   7. The inflorescences of ‘00-100-216’ are frost tolerant.

In comparison to the parent plants; the female parent, ‘89-98-13’, differs from ‘00-100-216’ in having yellow colored flowers, semi-double type flowers, and in having an upright plant habit and the male parent, ‘00-100-352’, differs from ‘01-127-1’ in having yellow colored, triplex daisy type flowers.

‘00-100-216’ can be compared to ‘Empire Salsa’ (U.S. Plant Pat. No. 9,578) for its inflorescence form and color, however ‘00-100-216’ exhibits a more uniform cushion plant habit (hemispherical shape), a larger plant size, greater winter hardiness and a massive floral display in its second and subsequent years after planting. ‘00-100-216’ can also be compared to other cultivars originating from the same breeding program with the common characteristics of cold hardiness and having a tight cushion form that becomes shrub-like in second and subsequent growing years; ‘00-100-382’ (U.S. Plant application Ser. No. 11803912)* exhibits single daisy-type inflorescences with dark purple ray florets and ‘01-127-1’ (U.S. Plant patent application Ser. No. 11803967)* exhibits single daisy-type inflorescences with light lavender ray florets. *Examiner has permission to update patent status and replace application Nos with patent numbers if applicable.

DETAILED BOTANICAL DESCRIPTION

The following is a description of plants the new cultivar as observed over 3 years on field grown plants in Waseca. The detailed botanical data was taken in October from one-year old plants grown outdoors in St. Paul, Minn. under natural lighting in 8-inch azalea pots produced from three cuttings that were pinched once in early spring. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of the Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
